Tundish refractory material
The tundish is an intermediate container between the ladle and the casting machine during the continuous casting of steel. It is used to temporarily store molten steel, evenly distribute molten steel to the casting machine, and adjust the flow rate of molten steel. It also plays the role of purifying molten steel, removing inclusions, and balancing temperature.
The refractory materials need to meet the requirements of high temperature resistance, anti-scouring, and anti-erosion. Zhenan provides you with tundish refractory materials, including nozzles, slides, and immersion nozzles, etc.

Ladle refractory materials
Ladle refractory materials are key materials used in the metallurgical industry to control the flow of molten steel. They need to have high temperature erosion resistance, wear resistance and good thermal stability.
During the steel smelting process, the nozzle, slide and nozzle are responsible for finely controlling the flow of molten steel. The nozzle controls the flow rate and flow of molten steel, the slide guides the metal to flow smoothly, and the nozzle achieves precise pouring.

Application of refractories in steel mills:
The continuous casting process of steelmaking is mainly used for the diversion and purification of molten steel and the improvement of the quality of ingots.
Production of special steel grades
It is suitable for the production of high-quality steel grades such as stainless steel, high carbon steel and alloy steel.
Steelmaking process
Ladle refractory materials are used for transporting and pouring molten steel, which are suitable for the production needs of ordinary carbon steel, high carbon steel, high alloy steel, stainless steel, etc.
Out-of-furnace refining process
It is used in refining processes such as LF furnace (ladle refining furnace), VD/VOD furnace (vacuum degassing furnace), etc. to ensure high-quality production of molten steel.
Our product advantages
We are a manufacturer specializing in providing refractory materials for the steelmaking and metal smelting industries. Our products include slide plates, nozzles, nozzles, etc., which are widely used in ladles and tundishes (including ladles in steelmaking processes and tundishes in continuous casting processes). These refractory materials play a key role in controlling the flow of molten steel, cutting off or opening the flow of molten steel, and ensuring production safety and efficiency.
Our slide plate system adopts the latest two-plate linear design, equipped with hydraulic or gas spring pressure system to ensure precise control of molten steel flow, extend service life and reduce maintenance requirements. Studies have shown that the life of traditional slide plate systems is a bottleneck, but our products have improved durability through optimized design and are suitable for high-requirement production such as high-carbon steel.
Our slide plates and nozzles are made of high-aluminum or aluminum-carbon refractory materials, which are resistant to high temperature and corrosion, protect the bottom of the ladle, extend the service life of the equipment, and ensure safe and efficient operation. The nozzles are made of high-quality materials such as alumina and zirconia to accurately control the flow of molten steel, reduce turbulence, keep the steel pure, and are particularly suitable for continuous casting processes.
Steelmaking and continuous casting: The sliding design regulates the flow of molten steel, ensures stable transmission from the ladle to the tundish, and reduces the risk of leakage and reoxidation.
Out-of-furnace refining: Protect the bottom of the ladle in highly corrosive environments and extend the service life of the equipment.
- High durability: High-performance materials such as Al2O3-ZrO2-C are used to extend the service life and reduce the frequency of replacement.
- Efficient operation: The two-plate linear design supports fast maintenance, reduces downtime and improves production efficiency.
- Reliability: The gas spring pressure system ensures sealing when closed, reducing safety hazards.
- Material: Al2O3-ZrO2-C, temperature resistance >1600°C.
- Specifications: Thickness 20-50mm, aperture Ø60-100mm, customizable.
- Morphology: Granular or blocky, particle size such as 0.2-1.0mm, 1-3mm, 3-8mm.
- By choosing our slide plate bricks, customers can improve production efficiency, reduce costs, and ensure high-quality steel production.
The nozzle is a key refractory component that connects the slide plate at the bottom of the ladle to protect the ladle from erosion by molten steel and slag. It is usually made of high-aluminum or aluminum-carbon materials, with high temperature resistance up to 1800°C and excellent corrosion resistance.
- Materials and performance: High-aluminum or magnesium oxide carbon materials are used to ensure structural stability, good thermal shock stability, and improve the purity of molten steel.
- Advantages: Provide long-life protection, reduce wear on the bottom of the ladle, and are suitable for continuous multi-furnace operation.
- Application: Used at the bottom of the ladle, in conjunction with the slide plate system to ensure safe flow of molten steel, especially in highly corrosive environments.
- High-quality products: all products pass rigorous quality tests, meeting and exceeding industry standards and reducing production disruptions.
- Customised service: sizes, materials and designs are adapted to meet the specific requirements of the ladle and intermediate packages.
- Technical support: a dedicated team provides process optimisation advice to help customers improve efficiency, such as optimising flow control to reduce turbulence.
- Cost-effectiveness: Durable products with extended life cycles reduce maintenance and replacement costs and are suitable for large-scale production.
- Industry experience: We have many years of experience in steelmaking refractory manufacturing, serving customers around the world and accumulating a wealth of case studies.
